* UCTL USB controller glue

Properties:
- compatible: "cavium,octeon-6335-uctl"

  Compatibility with all cn6XXX SOCs.

- reg: The base address of the UCTL register bank.

- #address-cells: Must be <2>.

- #size-cells: Must be <2>.

- ranges: Empty to signify direct mapping of the children.

- refclk-frequency: A single cell containing the reference clock
  frequency in Hz.

- refclk-type: A string describing the reference clock connection
  either "crystal" or "external".

Example:
	uctl@118006f000000 {
		compatible = "cavium,octeon-6335-uctl";
		reg = <0x11800 0x6f000000 0x0 0x100>;
		ranges; /* Direct mapping */
		#address-cells = <2>;
		#size-cells = <2>;
		/* 12MHz, 24MHz and 48MHz allowed */
		refclk-frequency = <24000000>;
		/* Either "crystal" or "external" */
		refclk-type = "crystal";

		ehci@16f0000000000 {
			compatible = "cavium,octeon-6335-ehci","usb-ehci";
			reg = <0x16f00 0x00000000 0x0 0x100>;
			interrupts = <0 56>;
			big-endian-regs;
		};
		ohci@16f0000000400 {
			compatible = "cavium,octeon-6335-ohci","usb-ohci";
			reg = <0x16f00 0x00000400 0x0 0x100>;
			interrupts = <0 56>;
			big-endian-regs;
		};
	};
